IMPROVEMENT IN LIQUID-SEALED vALvEs.

Specication forming part of Letters'iPatent No. 139,347, dated'May 27, 1873; application filed February 8, 1873.

Toull whom it may concern:

Beit known that I, LOUIS WINTERBAUER, of the city, county, and State of New York, have invented.V a new and useful Improvement in Liquid-Sealed Valve, of which the following is a specification:

Figure 1 is a detail section of my improved valve, shown as applied to a beer-cash. Fig. 2 is a detail horizontal section of the same vtaken through the line w a", Fig. 1.

Similar letters of reference indicate correspondin g parts.

The invention relates to barrels or casks of fermented liquors on draft; and consists in allowing the ingress of air to till the vacuum made by the withdrawal of liquid while the egress of the gases is prevented, as hereinafter described and pointed out in the claim.

A represents a plug or spigot, which is designed to be driven into a hole in the upper side of the cask or vessel, and which is made with a projection or arm upon each side for convenience in drawing it out when required.

a. is a channel or passage leading up from the inner end and out through one of the arms of the said plug A, which arm is so formed as to 'receive the end` of a small rubber tube, B.

` D is a small tube connected with a hole in the bottom c and extending up to a convenient height along the side of the body of the case C,

side. The Weight Fis secured to a rubber i flap, G, which is secured to the bottom c by the same pin that secures the ila-p E to said bottom.

In using the valve the case C is half filled,

more or less, with water, or other suitable liquid, so as to closely seal the valve. This construction entirely prevents the escape of gasfrom the cask or vessel, and at the same time allows the air to pass in freely to take the place of the `liquid drawn from thecask. The agitation of the liquid in the valve by the in-rushing air keeps the valve-seat and valve-aps Washed clean so that they will always it closely and be perfectly tight.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- The case C c having flap-'valve and open tube D, the iiexible pipe B, and the hollowplug A, combined and applied to a cask of fermented liquor, substantially as andwfor the purpose described.

LOUIS WINTERBAUER.
